No, Steve, it doesn't have to be a freewheel at all. The Grand Bois 120mm cassette you found is amazing. I had no idea that such a thing existed. It really is ideal. I really wasn't relishing the use of a freewheel, mainly because they don't seem to be made anymore. And with the Grand Bois I can get an extra cog tucked in back there, which is nice. The rear spacing of this bike has been the sticky wicket in the whole 700C conversion project. It made no sense to me to go to all the effort and expense of ditching the 27" wheel, only to keep the freewheel. Thanks for the info!
